Last week Gov. Jerry Brown declared California’s five-year drought over while proposing new long-term water conservation measures that must be passed by the Legislature. All Californians can be relieved that the drought has finally passed. Unfortunately, the state’s arid climate and its history all but ensure that it will return, so continued conservation measures are not unwarranted. But Brown let pass a perfect opportunity to remind legislators and the public at large about the urgent need to build more water storage in the state.
